Special Issue: Adaptive Service Discovery and Composition in Ubiquitous and Pervasive Computing

Ubiquitous and Pervasive Computing (UPC) are recent paradigms with a goal of providing computing and communication services anytime and everywhere. In UPC, automatic service composition requires dealing with four major research issues: service matching and selection, coordination and management, scalability and fault tolerance, and adaptiveness to users' contexts and network conditions. The articles in this special issue cover some of these topics and constitute a representative sample of the latest developments in adaptive service discovery and composition in UPC.
